`To all whom it may concern:

Be it known that We, EDWARD G. BUDD and JOSEPH A. WoLL, both citizens ofthe United States, and both residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, haveinvented certain new anduseful Improvements in Cushions, of which the following is aspecification.

This invention concerns cushions such as are used for the seats andbacks of car-seats and the object of the inventionl is to improve theconstruction of cushions of this type to4 the ends that a structurepossessing great strength and which can be manufactured at small cost isobtained. l

Our improved cushion comprises a frame which is formed of sheet-metalframe sections secured together at their ends, springs supported uponthis frame and suitable covering material overlying and yieldinglysustained by these springs. tions of the frame preferably consists oftwo sheet-metal members having coacting flang`es at the edges by whichthey are secured together and formed to provide an open space betweenthem, and these members are interlocked in such a way that relativemovement- .thereof lengthwise of the frame sections is precluded. Thecovering material of the seat is secured direct-ly to this frame as bysewing or tackingit thereto, holes being provided in the frame for thispurpose. In order that the upper edge of the cushion will readily yieldto the pressure, lthe frame of the cushion does not extend up to theupper edge, but instead, a thin strip of metal is employed runningaround the entire upper edge of the cushion. This strip may be sustainedin position by securing it to the ends of the flat springs commonlyprovided extending over and secured to the upper ends of the spiralsprings. `To further prevent relative displacement of the parts thisstrip may be covered with a suitable textile material and the coveringof the cushion sewed thereto.

The preferred embodiment of our invention is illustrated in theaccompanying drawings, in which Figure 1 is a top view of a cushionbroken away and sectioned in part, Fig. 2 is aseotion on line 2 2 ofFig. 1, Fig. 3 is a side Each of the sec-` view of the cushion brokenaway and sectioned in part, and Fig. 4 is a perspective view of one ofthe members of a frame section.

Referring to these drawings, the parts of the cushion are supported upona rectangular metallicV frame consisting of side sections 1 and endsections 2. Each of these sections is formed of two members, the lowermember 3 being provided with-flanges 4 at its edges and the upper member5 with folds 6 coacting-with these flanges to secure the two partstogether, the two parts being so formed intermediate their edges that anopen space is provided between them, thus giving greater strength to theframe section as a whole. The two members 3 and 5 are interlocked insuch a manner that movement thereof one on another lengthwise of thesection is prevented; this may be readily effected by indenting thecoacting flangesand folds as indicated at 7. The several frame sectionsmay be secured together at their ends in any suitable manner; this ispreferably done by providing overlapping portions at the ends as shownin Fig. 1 and collars lying within the frame sections at these points,into the ends of which the material of the overlapping portions is sunk.Extending between the side sections 1 of the frame are a plurality ofchanneled transverse rails or slats 8 secured at their ends, as byrivets, to the inwardly extending flange on the frame sections, andmounted upon these slats and upon the members of the frame are aplurality of spiral springs 9. Secured upon the upper ends of thesesprings and extending across the frame are a plurality of flat springs10, each of which may, if desired, be covered by a strip of textileniaterial to prevent it from cutting the overlying covering. Lyingdirectly above the cushion frame and extending around the -entire upperedge ofthe cushion is a strip 11 of thin flexible sheet-metal which issustained in position by riveting it to the ends of all of the iiatsprings 10. This strip 11 is preferably covered with canvas 12 or otherfabric for a purpose hereinafter described.

Overlying the flat springs 10 and the edge strip 11 is a covering whichmay consist of a piece of heavy felt 13, a covering of coarse fabric 14usually termed the f first canvas and an outer covering 15. W e will nowdescribe the means which we employ for securlthe covering in position.Before assembling the parts of the frame-sections, we provide in thelower frame-'members 3 a series of openings, as shownat 16, Fig. 4,preferably staggered to avoid weakening the member along this line, -andalso we provide a line of openings 17 in the4 vertical flange ofV theframe-sections formed by the outer flan e on the member 3 andthecorresponding fo d in the member 5. When the covering of the cushion isapplied thereto, the first canvas 14 isidrawn down tight on all sides ofthe cushion and is sewed to the vertical flange of the frame through theopenings provided therein as indicated at 18. If desired, the feltinterposed between `the first canvas and the springs may be of the samesize as the first canvas. and may be sewed to the frame in the sameoperation. .'VVhen this has been done,

the outer covering 15 is drawn down tight .over the first canvas and itsedge carried under `the bottoni of the frame.' Tacks19 are then driventhrough the covering 15 and into the openings 16 in the frame to holdthe covering in proper position. These tacks become wedged in theopenings in the frame and are held firmly, but if desired provision maybe made for turning the ends.v of the tacks over upon the insidegof theframe-section. 'The outer covering 15 of the cushion is often providedwith a beadin 20 at the to edge of thecushion and in oriIer to insureall the parts being held in proper relation, we sew this beaded edge tothe-first canvas 14 x and felt 13 or the coverin thereof as indicated at21, and sew the fe t to the covering 12 ofthe flexible metallic strip11, as indicated at 22. f A seat cushion constructed in this manner Y isof ample strength to withstand the severe usage to which it is subjectedand the edge of the cushion as well as the top will yield to pressure;moreover the means described for securing the covering material totheframe permits of quickly and securely assembling the arts at smallexpense.

' l aving 'now described our invention, what We claim as new therein anddesire to secure by Letters Patent is as follows:

' .1. A rectangular metallic frame consisting .f

i of four frame-sections secured together, at

` their ends and each consisting of a plurality of sheet-metal stripssecured together at their edges and bent longitudinally to provide openspace between the sides of the section and a flange running lengthwiseof the section, said flanges each having a series of o eningstherethrough, slats extending across t e frame, spiral springs mountedon the frame, flat springs supported by said spiralsprings, a coveringoverlying said flat springs and asewing interlacedthrough the coveringand the openings in said flanges to secure the fcvering to. the=fraine,substantially as set forth- 2. .In a cushion, a rectangular metallicframe having a flange -at the outer edge thereof substantiallyperpendicular to the plane of the frame and openings through saidflange, springs supported on said frame, a covering overlying said srings, and a sewing interlaced through sai covering and the openings inthe flange of said frame for holdin the ed es of the covering firmlythereto, su stanti ly 'as set forth. 3.
